ASSIGNOR TO PARAGON FIBRE COLORING- COR-POBATION, OF NEW YORK, N. Y., A CORPQRATION OF NEW MULTICC LOR-PRINTING MACHINE.

Application filed October 12, 1912.

To all whom it may concern -Be it known that I, E'wnL T. NEBEN, a citizen of the United States of America, and resident of the city of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improve- ;ments in 'Multicolor-Frinting Machines, of

which the following is a specification.

My invention relates to multi-color printim; machines.

The object of my invention is to provide a machine for printing surfaces of various descriptions, such as a web of paper or fabric or other substance that may be moistened on the surface, either in a continuous roll or sheets, in variegated colors, and to produce a novel printed surface thereon-by means of my improved printing machine and ha'snot, so far as I am aware, been produced'heretofore.

My invention consists in providing a printing member either in the form of a roll or plate or bar, composed of a soluble variegated composition; in providing means for feeding the surface to be printed across or in contact with said printing member, either yin slipping contact or non-slipping contact as may'be' desired; in providing means for supplying moisture in regulated amounts to the surface to be printed; in providing means for varying the effect of theprinting by changing the relative speeds of the printing member and of the printed sur face; and in other novel features and conto be hereinafter more fully pointed out and described.

In the drawings accompanying and forniing part of this specification Figure 1 is a side view of the preferred form of a multi- 0 color printing machine embodying my invention; Fig. :2 is a front view of the same; -Fig. 3 is a partial section on line 3 3 of Fig.1 Fig. -l is a partial section on line -tl of Fig. i; Fig. 5 is an end xiew of the nut 20; and Figs. (3 and 7 are side and rear views respectively of a modified form of the machine.

Numeral 1 represents the. side frame of the machine, secured to whichare the bracle ets 2, which form a support for a roll 3 of paper or ol her material. the surface of which is' to be printed. The material from the roll is led over a guide roll 4 and around'thc impression roll 5. The roll is m... Specification of Letters Patent.

mounted on the shaft 6, which is journaled 5i 1n the bearings 7. The impression roll preferably has a covering 8 of Vulcanized rubber, in order to make better contact with the web 3. The roll is driven by a chain 9 operating on the chain wheel 10, secured to the shaft 6 and connected with any con- Mounted in vertical guides 11 of the frame, are the bearmgs 12, in which is journaled the shaft 13,

which. carries the printing roll 1%. The as printmgroll'll preferably consists of a composition winch 1s relatively hard and tough and possesses such. a degree of solubility that when it comes in contact with a moistened surface it readily gives up its color thereto, and it is generally composed of a number of differently colored masses of composition variously arranged and molded together into a compact form, so as toproduce' a variegated or vari-colored mass.

The bearings 12 are provided with extensions 1:") having threaded holes in their ends. and the sleeves 16 are provided with oppositely threaded holes in their lower eiuls. A screw. 17 having a right hand thread at one end and a lefthand thread at the other engages the sleeve 16 and the extension 15 of the bearing12, and by means of these screws the printing roll 14 may 7 have its ends adjusted independently so as to bring it into proper alinementwith the impression mum. The upper ends. of the sleeves 1(5 are' provided with.transversely milled-grooves 18 which engage the lugs 19 1 on the nut 20, so that the sleeves 16 are prevented from turning and are carried up and down with thenut 20 and may be readily disengaged from the nut 20. .The upper portions of the nuts 20 are rectangular in section and enter arectangular hole in the 9- transverse web 21 of the cap 22. The caps 22 are provided at their-ends with pins 23 'on which are pivotally secured the clamps 24 which, by means of the thumb screws 25, hold the caps 22 in position on the frame. The screws 26 have beveled pinions 27 secured to their upper ends and having their' lowerends in threaded engagement with the nuts 20, are operated by the pinions 28 on the shaft '25.), having a handle 30 secured to 105 its end. By means of this construction both ends of the printing roll may be simultaneously raised or lowered.'

vand out of engagement with the gear 31 on the shaft 13. The operating lever 35 pivotally mounted in the bracket 36 and having a forked end 37 engages the grooved hub 34: to effect the engagement and disengagement of the gear 32 with the gear 31. The shaft 33 is rotatably mounted in the bracket 38 and has the worm gear 39 secured to its end. The shaft 40 carrying the worm ll which engages .the worm gear 39,

' is mounted in brackets secured to the frame of the machine and has secured to it a cone pulley 42 connected by the belt 43 to the cone pulley 4 on the shaft 45. A belt pulley 46 also mounted on the shaft 45 is connected by a belt 47 to a pulley 48 se cured to the end of the shaft 6. By means of these connections, when the gear 32 is thrown into engagement with the gear 31, the printing roll 14.- will be caused to revolve at a speed relative to the speed .of the impression roll 5, depending upon which step of the cone pulleys the belt as rests, and in general I prefer to have all of the speeds resulting from this connection proportioned so as to give a slower peripheral speed to the printing roll than the peripheral speed of the impression roll. It will be readily understood that the impression roll 5 serves the purpose of bringing the paper into printmg contact with the'printing roll and the further purpose of feeding the paper across the face of the printing roll. When it is desired to have the periphery of the; printing roll travel at the identical speed of the periphery of the impression roll, the lever 35 is operated to throw the gear 32 out of cngagci-ncnt with the gear 31, and the printing roll is then caused "to revolve by its frictional engagement with. the paper and impression roll. The printing roll will then print upon the paper the'exact design corresponding to the arrangement of the differcntly colored masses which compose the roll. When, however, the printing roll is caused to revolve at a slightly slower peripheral speed the design will be somewhat elongated and a marblcizcd ell'ect will be produce .l, and when the printing roll is given a very much slower peripheral speed, or if it is held stationary various streaked effects are produced.

llelow the impression roll 5 each side of the frame is provided with a vertical slot 4!), 1n \VllH'll 1H mounted a bearing 50 sup porting the shaftf fl, on which the moistenmg roll 521}? mounted. 'llns roll is preferably covered with felt and its lower-edge dips into the tank 53 which contains water. A cap 54 bolted to the frame across the lower end of the vertical slides 49, carries the screw 55, which is in threaded engage ment with the bearing 50 and has a bevel pinion 56 secured to its lower end. This beveled pinion meshes with the beveled pinion 57 secured to a shaft 58, at the end of which is secured an operating handle 59, by

means of which the moistening roll 52 may be raised and lowered. In order that the amount of moisture or Water carried by the moistening roll 5211p against the surface of the paper. which passes around the impression roll 5 may be regulated, I provide a roll 60 mounted in an oscillating frame 61, said frame being pivoted on the shaft 62, which shaft has bearings in the side frame 1. The shaft 62 projects through one of the side frames and has secured to its end a lever 63 and a screw 64 is in threaded engagement with the lug 65 on the frame and has a hand wheel 66 secured to its end, and passes through a. hole in the end of the dever 63 and is provided with collars 67 on either side of the lever, by means of which the regulating roll 60 may be moved into and out of contact with the moistening roll 52, or the amount of pressure of the regulating roll upon the moistening roll may be varied so as to permit the moistening roll to carry more or less water up to the paper, as may be required.

In the modification shown in Figs. 6 and 7, the variegated printing composition is molded in the form of a plate or bar, and held in a receiver in contact with the surface to be printed upon as the latter is passed under it in a moistened condition. In this embodiment of my invention, in lieu of the cylindrical printing roll 14, I provide a fiat bar or plate 68 composed of the same c0mposition in variegated colors. This plate is received into the chamber 69 between the transverse plates 70, and its lower edge rests upon the surface or web 3 which is to be printed. The upper end of the composition plate 68 has scoured to it by means of the clamps 71 or otherwise, flexible 'cords 72 which pass over the pulleys 73, where they are secured to the countcrnveights 74. The counterweights 74: may be increased or diminished to give the appropriate pressure between, the composition plate 68 and the 1 web 3. By means of this construction a great variety of novel and pleasing streaked ell'ccts is produced, at a very small expense.

Having thus described my "invention, what I claim is;

l. A multicolor machine for producing fancy variegated designs on a moving moist web of paper or tcxtilc l'al'nic, comprising an impression roll rotatably nioimtcd ina lixcd position. a compact variegated printiuj r ll rotatably mounted and contacting with the moist passing web, and means for driving 'a'the printing and impression rolls at different peripheral speeds. 5 '2.
